Show module.section+offset next to addresses in exception/stack-trace logs

Browse Source 
Added KernelModuleAddressDescription() (Core/HLE/sceKernelModule.cpp),
which looks up which currently loaded module (and text/data/bss/segment
section within it) an address falls in, e.g. "EBOOT.BIN.text+1234".
Wired it into:

- Core_MemoryException/Core_ExecException/Core_BreakException
  (Core/Core.cpp), appended next to every address/pc/ra shown in their
  log lines.
- FormatStackTrace (Core/MemFault.cpp), appended per-frame next to the
  existing symbol description.

This makes crash/exception logs actionable even when there's no symbol
at the faulting address - you at least get which module and section
it's in, useful for reverse engineering unfamiliar code.

Verified live via headless: injected a MIPS break instruction at the
current PC (through Tools/wsdbg) and confirmed the log line changed from
"break instruction hit at 088040ac" to "break instruction hit at 088040ac
[sceDisplayWaitVblank Test.text+ac]".
